Flower essences, sound essences, solarized water, are all potentized/charged liquid (usually spring water, plus a preservative) that holds the energy of the flower, stone, or color used to charge it. This provides a simple, portable solution to applying those energies to a person, place, thing, or situation. They are a holistic or vibrational form of supporting the body, mind, and spirit.

These essences are specifically the essences Dr. Bach developed in the 1930s.
